6 Cllllml.

The shaft ofthe screw I4 passesthreugh the gaged by a door when the door is swungopen slot I2 and has screw-threaded engagement with 5 for the purpose ofcushioning the impact of the apost I1. which is interiorly threaded'atone end 5 door and stopping it from striking the wall, and to eigagesaid bolt. The opposite end of the post particularlythe inventionrelates to a device of is formed with a socket I8 for engagement withthis character which is so formed as to provide the screw-threaded shankof a bolt I9, thehgad not only a stop but a holder which will engage 2IIof this bolt being embedded within the central* 10 the door when thedoor is swung fully open and portion of a rubber suction cup 2l.

Figure 1 is a top plan view of the stop and a 1t will be seenthat the ilange 29 forms a sockportion 0f the skirting board, the doorbeing et for the reception of the hemi-spherical boss II 35 shown indotted lines. and that the face I6 of the screw head I5 bears Figure 2is a vertical section through the stop. against and conforms to thecurvature of the in- Figure 3 is a. face view of the base of the stopner face of this boss II.

When the slighty(lished/s0 that the central portion of the door B is swung open andtoward the wall, the base is out of contact with the base board A anddoor will strike one margin of the suction cup 2| only the periphery ofthe base comes in contact and this will cause the door stop t0 Swingfreely with the base board. By dishing the base, as deto the positionshown in dotted lines in Figure 1, 5o scribed, the screws will moretightly hold the base and the further movement of the door will cause,to the base board A than it the base were dat. the attening of thesuction cup against the face'V Extending through the slot I2 in the bossI I is a of the door. The impact of the door against the bolt I4 havinga head I5, that portion of the suction cup will force the section 24 ofthe shell head connecting with the shank of the bolt being 'inwardagainst the action of the spring 30 and 55 the door against the suctioncup will act to hold the door in piace against the stop until the dooris manually or forcibly pulled away `from the suction cup. The air,thatis'enclosed within -the shells 24 and 21 will be forced out through theends of the slot i2 and into the space between thedishedbaseandtheiaceofthebaseboardA, thus acting as a pneumatic cushion.

It will be seen that by rotating the bolt Il by means of the head I5,the post I1 may be drawn inward and this will draw the suction cupinward and force the shell section -24 inward into the shell section 21,thus this device has a certain lrange-of adjustment and may bere-adjusted from time to time by removing the screws holding the base tothe base board A, then re-setting the screw I4 to the desired amount.

In actual practice, this structure acts as stated. in that if the doorbe forcibly thrown open against the suction cup, the blow of the doorwill be cushioned and the suction cup will hold the door from reversemovement until the door is pulled open. Y.

What is claimed is:- l

1. A door stop and holder, including a b ase for attachment to a baseboard, a two-part shell, one section of which has free rockingengagement with the base at all times. the other section havingtelescopic engagement with the nrst named section, a spring urging thesections outward relative to each other and resisting inward movement oithe outer section, and a suction cup attached to the outer end 'of thesecond named section.

2. A door stop and holder, including a base formed for attachment to thebase board of a room, a two-part shell, one section oi' which has freerocking engagement with the base at all times, the other -section havingtelescopic engagement with the ilrst named'section, a spring disposedwithin the sections bearing against the inner section and urging theouter section outward, .a suction cup attached to the outer end of theouter section, and means hunting the outward movement of the outersection under the action of said spring.

3. A door stop Aand holder, including a base i'ormed for attachment tothe base board of a room, a two-part shell, one section of whichhas freerocking engagement with the base at all times, the other section havingtelescopic engagement with the ilrst named section, a spring disv posedwithin the sections bearing against the inner section and urging theouter section outcenter of the suction cup and extending loosely throughsaid sections of the shell and having rocking and sliding engagementwith the base.

4. A door stop and holder, including a base having means whereby it maybe attached to a base board, the center of the base having ahemi-spherical boss formed with a transversely extending slot, a shellformed ot two telescopically related sections, the inner section of theshell having, a central opening and formed with an inwardly extendingannular flange forming a socket coacting with the hemi-spherical boss,the socket being free to swing upon the boss at all times, a suction cupmounted upon the outer end oi the `outer section of the shell, a springdisposed in the shell and urging the outer shell tioncup and the bossand limiting the outward movement of theouter section ofl the shell withits suction cup but permitting inward movement of the outer section ofthe shell and the sucscopically related sections, the inner section ofthe shell having-a central opening and formed with an inwardly extendingannular flange forming a socket coacting with the -hemi-spherical boss,the socket being free to `swing upon. the boss at all times, a suction cup mounted upon the outer end of the outersection oi the shell, a springdisposed in the shell and. urging the outer shell outward, a post havinginterior screw-threads at its inner end and disposed within the twosections of the shell, the outer end ofthe post having means foranchoring it to the suction cup, and a bolt extending through the slotof the boss and having screw-threaded engagement with the post, the.bolt having a head, the outer face of the head being rounded to tagainst theinner rounded tace of the boss.

6. A door stop and holder, including a, base for attachment to a baseboard, a two-part shell, one section of which has free rockingengagement with the base at all times, the other section havingtelescopic engagement with the rst named section, a suction cup engagingthe outer end oi' the second named section, and means urging thesections outward relative to each other.
